Check if user context is array (fix fatal error) (#272)

* Check if user context is array

Prevents potential fatal error as the argument for Scope::setUser  must be of type array

* Make sure user is always an array

If user array is invalid, Sentry will display a warning.
This ensures the context is not silently ignored.
